CHECKING THE SERVICE
LOG
Checking the service log consists of viewing the entries written into
the log.
CAUTION
The service log contains historical information about instru-
ment condition and any failures that may have occurred. It
should be cleared only by a qualified service engineer. Such
clearing should be accomplished only upon determining that
the errors need not be saved to disk, or printed out for service
purposes.
Procedure:
Step 1. Press the Option Menu key (Enhancement key group) to
display the OPTIONS menu.
Step 2. Select DIAGNOSTICS from menu (left); then select
READ SERVICE LOG from the DIAGNOSTICS menu.
The VNA will now display the contents of the service log.
The display consists of a header and an error listing. The
header contains a variety of system service information.
The error listing contains error messages for failures that
may have occurred during operation.
NOTES
·
Errors 7201 to 7209, GPIB remote opera-
tion programming errors, report that one
or more external GPIB programming er-
rors has been detected. These messages
do not indicate a VNA system fault.
·
Informational messages 0000 to 0099 re-
port the pass/fail status of a peripheral
access. These messages do not indicate a
VNA system fault.
Any other error messages in the service log may indicate
an instrument problem and should be investigated. Refer to
Chapter 7, Troubleshooting, for further information.
CAUTION
The CLEAR SERVICE LOG menu selec-
tion will immediately and permanently clear
all the error message entries from the ser-
vice log. (However, it will not clear the
header information.) See Caution message
at top of page.
